Ereditarietà | UITextFormat TextFormat Object |
Versione linguaggio: | ActionScript 3.0 |
Versione prodotto: | Flex 3 |
Versioni runtime: | Flash Player 9, AIR 1.1 |
The UITextFormat class extends the flash.text.TextFormat class
to add the text measurement methods measureText()

antiAliasType | proprietà |
public var antiAliasType:String
Versione linguaggio: | ActionScript 3.0 |
Versione prodotto: | Flex 3 |
Versioni runtime: | Flash Player 9, AIR 1.1 |
Defines the anti-aliasing setting for the UITextField class.
The possible values are "normal"
(flash.text.AntiAliasType.NORMAL
)
and "advanced"
(flash.text.AntiAliasType.ADVANCED
).
The default value is "advanced"
,
which enables advanced anti-aliasing
for the embedded font.
Set this property to "normal"
to disable the advanced anti-aliasing.

The allowed values are "ltr"
for left-to-right text,
as in Latin-style scripts,
and "rtl"
for right-to-left text,
as in Arabic and Hebrew.
FTE and TLF use this value in their bidirectional text layout algorithm, which maps Unicode character order to glyph order.
